"The greenhouse effect is extremely
doubtful"[Danish:Drivhuseffekten er yderst tvivlsom].Bjørn Lomborg in his `break-through´ article, "The
true state of the planet", Politiken, Denmark, 12th Jan. 1998.

On Lester Brown´s pessimistic prediction of future
trends in wheat
yields: "Also, and this is ironic, the very year Brown made his
statement, wheat yields broke through the previous wall, and have since
then been above the "maximum" every single year save one." - 2001, TSE
p. 97.

"Thus, it is also expected that
the oil price will once again decline from $27 to the low $20s until
2020."
- 2001, TSE p. 122.

ABOUT CRITICISM

In response to the review in
Nature:

"Basically, the question to ask Pimm & Harvey seems
to be: if I really am so wrong, why don´t you just document
that?"

On
the FAQ page on www.Lomborg.com, commenting on Lomborg-errors:

"However, with limited time,
Lomborg cannot reply to every new claim from Fog. Moreover, it would
seem reasonable that Fog would have used his best counterarguments
first, and clearly these have not stood up."

About David Pimentel:"The Pimentel article repeatedly
makes the mistakes we have talked about above, but most
importantly it is wrong and seriously misleading on all of its
central conclusions. However, this has not hindered the article
in being cited and frequently used in pointing out the decline of
the world." - The Skeptical Environmentalist (TSE) p. 22.

About Stephen
Schneider, John P. Holdren, John Bongaarts and Thomas Lovejoy
In response to the editor of Scientific
American who asked four leading experts to critique Lomborg´s
treatment of their areas: "Notice that these four editors have
certainly not been chosen randomly - two of the four reviewers
are actually directly criticized in my book. . . the obvious lack
of any concern for presenting a balanced review of my work calls
into question the real purpose of this Scientific American
feature." - Lomborg´s reply to Scientific American, 16th
February 2002.

About Stefan Rahmstorf, lead
author of the paleoclimate chapter of the 4th assessment report of the
IPCC:
"Rahmstorf is a well-established, serious researcher on climate change
who holds a minority view on the rise in the sea-level."
